IMPROVEMENT IN CLAMPING AND NAILING WASH-BOARDS.

Specification forming part of Letters Patent N0. 38,41 I, dated May 5, 1863.

' have invented a new and useful machine for clamping and nailing in the manufacture of zinc Wash-boards; 4and we do hereby declare that the following is a full and eXact description of the same, reference being had to the annexed drawings, making apart of this specification, in which- Figure l is a perspective view of the whole machine. Fig. 2 is a view of the shaft. Fig. 3 is a view of the clamps (sliding.) Fig. 4 is a view of the clamp, showing the lian ge. Fig. 5 is a transverse view of the machine.

Our clamping and nailing machine is of simple construction and easily understood, it being placed simply on a stout shaft, A, Figs. l and 2, upon two standards or posts, B B, Fig. 1, fastened to the floor C, Fig. l. This shaft A has two little cams, D D, Fig. 2, hereinafter more fully described. The clamps E E, Fig. l, are made of heavy boiler-iron, fourteen inches wide and sixteen inches long. Two inches of one end of each piece is turned at right angles upward to form a clamp. These plates are put together with little bolts, (not shown,) fastened in the upper plate and passing through a slot in the lower to allow them to move. There is a portion, F F, Fig. 3, taken out of the center of each side of the lower plate, so a sto move past the bearings of the shaft that is fastened to the upper plate. To the lower plate is fastened rmly straps or yokes H H,into which small cams work on the said shaft A. Attached to the upper plate is a piece of boiler-iron, I, Fig. 1, eleven inches wide and twenty-four inches long inside the turns on each end. This piece is for holding the side pieces of the wash-board to their places lengthwise while clamping and nailing. On the end of the shaft A, at the right hand of the operator, is alever, K, fastened. When this lever is from the operator, the cams DD on the shaft A moves the lower plates outward, Wideniig the space between the flanges or clamps E E on the outer ends, and when the lever is turned toward the operator the plates or clamps are drawn back and the space between the clamps contracted. In front and between the two standards or posts, B B, stands a resting-post, L, on which the front side of the clamps rest while placing in the material and clamping. Theclamps are turned with the shaft on the standards (without effecting the clamps) from the operator till tlie clamps stand perpendicular, presenting the edge in t-he right position to nail the wash-board, which is done through holes in the flanges for that purpose. The said resting-post L is made elastic, so that the clamps can be turned down the other way past it for nailing the other side.

The operation of our` clamping and nailing machine is very plain and simple. The two side pieces of the wash-board are laid on the clamps against the iianges E E, the back piece is laid between them in the centerlengthwise, the lever is drawn over by the operator, bringing the cams D D in contact with the yokes H H. The clamps are drawn powerfully together and the zinc plates pressed hard against the back board. The clamp is turned first upon one edge, then upon the other, and nailed through the holes represented in Fig 1. The clamp is then loosed and turned to its original place on the restingpost, the lever being thrown over from the operator, relieving the board for another operation.

After having thus fully described our clamping and nailing machine for wash-boards, what we claim as new, and desire to secure by Letters Patent, is-

The sliding clamps E E, standards or posts B B, with the lever L and cams D D, in the manner and for the purposes set forth.

This specication signed and witnessed this 12th day of December, A. D. 1862.
